IMPROVEMENT IN APPARATUS FOR OlLlNG SPINDLES.

` Specication forming part of Letters Patent No. 159,499, dated February 9, 1875; application liled October 9, 1874.

To alt whom it may concern:`

Be it known that we, CEAS. Gr. BUTTRIOK and TIMOTHY B. FLANDERs, of Holyoke, Massachusetts, have invented Improvements in Apparatus for Oiling Spindles; and we do hereby declare the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section (partly in view) of our improved spindle-oiling apparatus. Fig. 2 is a horizontal section on line w w of Fig. 1. Fig. 3 is a similar section on line a; of Fig. 1. Fig. 4. is a similar section online y y of Fig. 1. Fig. 5 is a similar section on line zz of Fig. l. Fig. 6 is a perspective view of the bearing which receives and supports the lower end of the spindle.

The same letter indicates the same vpart Wherever it occurs in the drawings.

Our invention consists in the peculiar construction, hereinafter set forth, ofthe bolster, whirl, cap, step, and bearing of a live spindle for spinning-frames, whereby We are enabled, by supplyingoil at a single pointa g., the top ofthe bolster--to perfectly lubricate the upper and lower spindle-bearings, to keep the lower end ofthe spindle submerged in oil, and to conduct oft' and save the surplus oil in a reservoir, whence it can be drawn at pleasure for repeated use, all as hereinafter more fully set forth.

In the accompanying drawings, which fully illustrate our invention, S marks the spindle, Which may be of any form preferred. Bis the bolster, set in the bolster-rail R, and extending down into the top of the whirl W. In the upper part of the bolster is an oil cup or chamber, 0, which communicates by means of two holes, c a, with the bore of the bolster. The Whirl W, which receives the lower end of the bolster, is fixed upon the spindle in the usual way, and is provided With an undercut oilchamber, U. This form of the oil-chamber prevents the oil which itv may contain from being thrown out by centrifugal action during the rotation of the whirl. From the chamber U two tubular pert'orations, b b, are made through the body of the whirl to its lower chamber, which receives the upper end of the conoidal cap C, and the cupshaped top of a cylindrical sleeve, F. The lower ends of the tubes b b open into the cup on the upper end of sleeve F, so that all oil passing through the whirl is received by and passes down through that-sleeve. The lower end ofthe sleeve rests upon a nut, N, and is provided with two holes, n n, opening into the bore of the cap C. The lower end ot' the cap C is received by the upper end of the step A. It may be provided with a notch or notches to engage with lugs or pins within the step, to prevent the rotation of the cap with the spindle. The step A passes through and rests by a shoulder upon the step-rail D. Its upper portion forms a chamber, in which is placed the cup Gr, which forms the lower bearing ofthe spindle. From the bottom of this chamber, through the lower part of the step, passes a tubular` perforation, T, leading down into the oil-reservoir E, attached to the lower side of the step-rail D. The cup or bearing G is shown in perspective in Fig. 6. It consists of a cylinder having for its bottom a circular disk, which projects as a ange beyond the cylinder, and fits snugly the bore of the chamber of the step A. Wings w fw w w project from the outside of the cylinder, and abut against the inside of the chamber. Two holes, e e, perforate the cylinder near its top, to allow of the escape of oil into two of the four chambers formed by the cylinder, its wings, and the sides of the stepchainber. The other two of these chambers have notches i' 'o' in their bottoms, which open communication with the lower part of the chamber of step A, and through tube T with reservoir E. Reservoir E is a vessel of any suitable character attached to the lower side ofthe step-rail to receive the surplus oil, and is removable at pleasure.

The operation of our invention is as follows: The oil for lubricating the spindle is introduced into the cup or chamber O in the upper end of the bolster. Thence it passes through holes a a into the interior of the bolster, and lubricates the upper or bolster bearin g of the spindle. It escapes from the lower end ofthe bolster into the cup U in the upper part ofthe whirl, and descends through tubes or holes b b into the interior of sleeve F through the cup in its top. lThrough holes n n in the lower end of sleeve F it passes into the bore of cap C. Thence it runs down into the step A, and lls vits chamber up to a level with the top of the wings w, lling the cup` or cylinder G, and keeping the lower end of the spindle submerged in flowing oil. The surplus oil escapes over the wings w, flows through the notches i t' and the tube or hole T, and falls into the reservoir E, whence it can be drawn when required to be used again.

Our improvements are attended with many advantages. There is a great economy in oil, labor, and time, as the surplus oil is entirely saved, and the oil is supplied at a single point only, the lubrication subsequently being automatic. The spindle is so covered as to be protected from clogging by waste, dirt, or loose fibers of the material used. Oil cannot be thrown either upon the frame of the machine, the banding, or yarn. So little oil escapes that very little wiping is required. The lower bearing being submerged in flowing oil, there is no opportunity for the accumulation of grit or other substances to produce friction. Finally, the oil is confined and controlled during its passage from the top to the bottom of the apparatus.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

1. The combination, with the live spindle of a spinning-frame, of the bolster B, whirl W, sleeve F, cap C, step A, bearing G, and reservoir E, all constructed, arranged, and operating substantially in the manner described.

2. The bolster B, having an oil cup or chamber in its upper end, communicating by a suitable orice with its bore, thebolster being so prolonged as to extend down through the bolster-rail into the top of the Whirl, as specied.

3. In combination with the cap G, the sleeve F, provided with a cup at its upper end, and with the holes n a at its lower end, for the purpose of conducting the oil from the Whirl to the step, as described.

4. The cup or lower bearing G, constructed as described, and provided with the wings w, holes e, and notched bottom disk, as and for the purposes set forth.

The above specication of our said invention signed and witnessed at Holyoke, Massachusetts, this 7th day of October, A. D. 1874.
